2.       We note your disclosures that the increase in net sales during the
current interim period
         was driven by growth in certain regions and end markets. We also note
your disclosure
         that this is the first full quarter of revenue from the LSC
acquisition. Please revise your
         disclosures related to changes in net sales to quantify and more fully
explain the reasons
         for changes in net sales during each period presented. For example,
please quantify the
         impact of sales related to the LSC acquisition and better explain the
underlying reasons
         for sales growth in certain regions and end markets.
       In closing, we remind you that the company and its management are
responsible for the
accuracy and adequacy of their disclosures, notwithstanding any review,
comments, action or
absence of action by the staff.
